Basically a hash consists of three main parts: The Run. One or two hashers mark a trail before the hash, or lay the trail as "live hares" running ahead of the pack with only a short head start. At a given signal, the rest of the hash set off in pursuit of the trail. The Circle. At trail's end hashers gather to drink beer. The Circle can last a couple of minutes or half the night depending on the level of the hash. The On-On. Some hashes suspend drinking for awhile to consume food provided by the hare(s), others repair to a nearby restaurant or pub.
